Erebus - Level 4: Erebus Control

Erebus - Level 4: Erebus Control is the fourth level of Doom 3: Resurrection of Evil.

Summary
At the start of the level, a survivor speaks to the marine from the vent shaft above, saying that the marine should power up the lift using two power cells to reach him and proceed further. The marine begins fighting his way through the level. In Adminstration Access, if he gets on the catwalk (using crates nearby), he can witness another survivor being killed by a vulgar. The marine has to grab his PDA to proceed to the transfer area. There, the marine is tasked with finding another power cell to power a conveyor elevator to reach the second floor. The power cell is found in Main Office nearby. After getting to the second floor, the marine proceeds through some administrative areas before reaching Debris Processing where he extends a bridge and finds a power plant that has two power cells in it. The marine takes the cells, returns to the start, and powers up the lift. However, after reaching the vent shaft the survivor who was waiting for the marine is found dead. Nevertheless, the marine uses the shafts to reach the exit room and takes the elevator to the next level.
